Answer:
The bus would be 36 times late in 400 times of when Fred takes the bus
Step-by-step explanation:
Given that the probability of being the bus late is 0.09.
In order to find the number of times the bus will be late will be calculated by multiplying the total number of observations by probability.
It is also given that the total number of days he waits for bus is 400 times.
So,
The bus will be:

Hence,
The bus would be 36 times late in 400 times of when Fred takes the bus
Answer:
Solution given:
In right angled triangle
ABC.
with respect to <C=40°
opposite side=AB
adjacent=BC=DE=30ft
now
relationship between opposite side and adjacent
is given by tan angle
tan 40°=oppo/adjacent
tan40°=AB/30
AB=tan40*30
AB=25.2
<u>Now</u><u> </u>
<u>height</u><u> </u><u>of</u><u> </u><u>flagpole</u><u> </u><u>=</u><u>AB</u><u>+</u><u>BE</u><u>=</u><u>2</u><u>5</u><u>.</u><u>2</u><u>+</u><u>5</u><u>=</u><u>3</u><u>0</u><u>.</u><u>2</u><u>f</u><u>t</u>

Answer:
C. f(x)=-2x^3-2x^2+12x
Step-by-step explanation:
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
